Title: Remote controller
IPC: G11B15/02
Filed: 1992-03-31
Abstract: PURPOSE:To enable recording in a relay system by inputting a specified particular of each VTR, video recording order for relay video recording, a residual amt. of time of a magnetic tape loaded in each VTR and video recording reservation of the whole of plural VTRs. CONSTITUTION:When all information required for performing relay system and long time video recording is inputted, the required number of magnetic tapes is calculated by a control part 16 based on video recording reservation information for each VTR. Then, the whole video recording time calculated from video recording starting time and video recording ending time of the whole of the plural VTRs inputted previously with the video recording reservation information and the whole residual amt. of time previously inputted are compared with each other, and when the whole residual amt. of time is smaller than the whole video recording time, the process is returned to the previous step before. Then, when reservation setting for each individual VTR is completed in the control part 16, this is transmitted from a transmitting part 18 to each individual VTR. Thus, by this remote controller, relay video recording in specified video recording order is feasible by transmitting a transmitting code to the plural VTRs.

Title: Manufacture of semiconductor device
Inventor: MORII HIROYUKI
IPC: H01L21/265
Filed: 1990-03-28
Abstract: PURPOSE:To eliminate occurrence of a defect due to an ion implantation and to obviate deterioration of electric characteristics such as breakdown strength of a well by dividing the ion implantation to twice, and reducing doses of the ion implantations to predetermined value or less. CONSTITUTION:P-type boron ions are, for example, implanted with a dose of 5X10<12> atoms/cm<2>, substantially a half of the dose aimed to be obtained through the opening of a mask 2. Then, a base 1 is heated to 900-1000 deg.C for one min. In this heating, the surface of the base is activated to recover a defect induced by the ion implantation while preserving an impurity profile as it is. Then, boron ions are implanted through the opening of the mask 2. The dose at this time is set to 5X10<12> atoms/cm<2> of the residual dose. Thereafter, the entirety is heated, for example, at 1100 deg.C for 20 hours to diffuse boron ions to form a p-type well 4 in the base 1. Thus, even if the defect due to the implantation is induced, it can be recovered by annealing.

Title: Sample holding device
IPC: B23Q3/15
Filed: 1992-03-31
Abstract: PURPOSE:To easily obtain an insulating film excellent in reproducibility to improve the breakdown voltage characteristic and the sample suction force by evenly forming it containing alumina as principal component over the entire surface of a conductor constituting a sample stage through electrochemical reaction in electrolyte. CONSTITUTION:A sample suction face 3 of a conductor 1 is polished, and then, the conductor 1 is anodized. Then an anodic oxide coating 2 of hard and dense alumina, called hard oxide film, is evenly formed on the entire surface of the conductor 1. Subsequently, sealing is carried out to fill fine holes existing on the surface of the anodic oxide coating 2. This makes an insulating film excellent in breakdown voltage characteristic. Further, the thickness of the anodic oxide coating 2 is considerably larger than that of the ceramic spraying film. With the decrease in film thickness, the electrostatic capacitance is increased between a sample and the conductor surface, enhancing the suction force of the sample suction face.
